Q

BOTH INTERNATIONAL & INLAND Which vessel may sound at least five short and rapid blast on the whistle if in doubt whether sufficient action is being taken by the other vessel to avoid collision?

🔍 Key Concepts

• Rule 34(d) – Doubt or confusion signal in the Navigation Rules (sound signals for maneuvering and warning) • The phrase “if in doubt whether sufficient action is being taken by the other vessel to avoid collision” – who can have that doubt? • Difference between vessel status (give-way, stand-on, at anchor, meeting, crossing) and the right to use a danger signal

💭 Think About

• Ask yourself: Does the Navigation Rule for five short blasts limit this signal to any particular type or status of vessel, or is it more general? • Think about the purpose of this signal: it’s a danger / doubt signal. In a real-world close-quarters situation, would it make sense to restrict who can use it? • Look up Rule 34 and read the wording carefully: does it say which vessel may make this signal, or simply what a vessel shall/may do when in doubt about the other vessel’s actions?

✅ Before You Answer

• Verify the exact wording in Rule 34(d) of the Navigation Rules – especially who it applies to. • Confirm whether a vessel at anchor is excluded from using this doubt signal anywhere in the Rules. • Check if there is any rule that reserves the five short and rapid blasts only for the give-way vessel or only for certain encounters (meeting vs crossing).
